Correlating the Molecular Structure of Polyimides with the Dielectric Constant and Dissipation Factor at a High Frequency of 10 GHz

Chih-Cheng Kuo et al.

Summary: This study extensively investigated the relationships between the structure and dielectric properties of polyimides, revealing highly correlated relationships between dielectric constant values and structural parameters such as fluorine content and volume polarizability. Additionally, a strong correlation was found between dissipation factor values and the imide group content. However, there were multiple positive trends in the relationship between dissipation factor values and volume dipole moment, attributed to the challenges in elucidating local molecular motions in the unit structure of polyimides.
